xu. PREFACE. 



forth this little book upon its mission. The best wish 

 I can have for it is that it may impart to its readers 

 a tithe of the pleasure its preparation has given to 

 its author. I may, perhaps, be allowed to hope, that, 

 it shall communicate some interesting knowledge to 

 many inquirers, and awaken in many appreciative 

 minds an intelUgent admiration for this part of Nature's 

 wondrous handiwork.
